Cool Vitamin D™ - Product Information

Vitamin D3 is recommended for maintaining and improving cellular and immune function, and bone and body health – without any of the harmful effects of too much sun* 

Winter Sun smVitamin D is an essential component for the body’s ability to achieve and maintain stable biological and cellular functions.  It plays a vital role in numerous processes that include: increasing the body’s immunity; bone development; increasing and maintaining bone density; regulating calcium and phosphate levels and neuromuscular functions; and assisting with cell mediation (the cell’s lifecycle).

Unfortunately, a significant amount of the Vitamin D3 supplements sold over the counter and compounded do not contain the stated amount (dose) (LeBlanc et al., 2013) because of poor manufacturing controls and unstable formulations.  These researchers found potencies as low as 9 percent and as high as 140 percent of the listed dose (Bakalar, 2103).
